New Hampshire's September Serenity: A Glimpse into Thursday's Weather

Good morning, New Hampshire! If you’re anything like me, you’re probably wondering what kind of day Mother Nature has in store for us as we officially push into mid-September. Well, I've got some delightful news for Thursday, September 10th, 2026 – it’s shaping up to be one of those absolutely picture-perfect days we all cherish here in the Granite State.

Forget those sticky, humid days of August. This Thursday, we're talking about a lovely transition day, holding onto just enough late-summer warmth while hinting beautifully at the crisp, clean air of autumn that's waiting just around the corner. It's that sweet spot, you know?

Wake up early tomorrow, and you might just catch a bit of that classic New England morning mist clinging to the valleys, especially if you're near a river or one of our many gorgeous lakes. It’s truly a sight, isn't it? That gentle shroud, it’ll burn off pretty quickly, though, as the sun makes its grand entrance. Expect temperatures to start off on the cooler side, hovering in the high 40s to low 50s, making that first cup of coffee feel extra cozy.

By mid-morning, we'll be basking under mostly sunny skies. Perhaps a few scattered, fair-weather clouds might drift by, but nothing to spoil the view. Temperatures are really going to climb quite comfortably, reaching the mid-60s across much of the state, and potentially even kissing the low 70s in our southern counties. Up north, you might stay a touch cooler, more in the low to mid-60s, which, let's be honest, is just perfect for a hike through the emerging fall foliage.

The best part? Humidity will be practically non-existent! So you can leave that sticky, heavy feeling firmly in the past. We’ll have a gentle, light breeze, just enough to rustle the leaves that are, by now, really starting to hint at their magnificent autumn colors. It’s the kind of day that just begs you to step outside, whether you're tackling a trail, exploring a farmer's market, or simply enjoying a quiet moment on the porch.

As the sun dips below the horizon, bringing with it those breathtaking New Hampshire sunsets, temperatures will begin their steady decline. Expect a wonderfully clear evening, cooling into the mid-50s by dinner time, eventually settling into the low 40s or even upper 30s overnight. This will be especially true in our higher elevations or out in the more rural spots. It’s definitely the kind of night where a light jacket or a cozy sweater feels just right, and if you look up, the stars truly put on an incredible show in our clear skies.

Looking ahead just a smidge, Friday and the start of the weekend appear to continue this delightful trend. Mostly dry, with plenty of sunshine to go around. So, if you’ve been holding off on those outdoor plans, perhaps a scenic drive or a final paddle on the lake, this might just be your golden ticket. Enjoy this beautiful slice of early autumn, New Hampshire!
